Description

Technical Field

[0001] The utility model relates to the technical field of agricultural breeding, in particular to an escape prevention device for a water outlet of crayfish breeding. Background Art

[0002] When breeding crayfish, the crayfish are placed inside a breeding pond. A drain outlet is provided at one end of the breeding pond to replace the water source inside the breeding pond. However, when the water source is replaced, the crayfish may escape from the drain pipe. At this time, a filter anti-escape device is required to prevent the crayfish from escaping.

[0003] The existing patent number CN202122654202.6 discloses that the utility model discloses an anti-escape device for a water outlet for crayfish breeding, which relates to the technical field of agricultural breeding tools. The anti-escape device for a water outlet for crayfish breeding comprises a protective cover and a water outlet pipe, the water inlet end of the water outlet pipe is located inside the protective cover, the protective cover comprises a fixed rib, a top ring and a base, the surface of the fixed rib is fixedly connected to the surface of the top ring, the surface of the fixed rib is fixedly connected to the surface of the base, a top cover is arranged above the top ring, the lower surface of the base is movably connected with a fixed component, the outer surface of the fixed rib is provided with a convex particle, the surface of the convex particle is movably connected with a filter component, the surface of the base is provided with an installation groove, and the inner wall of the installation groove is movably connected to the side surface of the water outlet pipe. By arranging the fixed component and the filter component, the problems of being difficult to clean when the anti-escape filter device is blocked and the unstable placement of the filter device are solved.

[0026] This embodiment provides a specific structure of a crayfish breeding outlet escape prevention device, such as Figure 1-5 As shown, it includes a protective tube 2 and an end cover 3 arranged at the top of the protective tube 2. The protective tube 2 and the end cover 3 are detachably installed, and a connecting end 5 is provided at the intersection of the protective tube 2 and the end cover 3;

[0027] Among them, a hole is opened inside the end cover 3, and a protective net 6 is embedded inside the end cover 3. The protective net 6 and the end cover 3 are an integrated structure. When water enters the interior of the protective tube 2, it flows out from the protective net 6, reducing the impact on the protective tube 2. An end cover 3 is provided at one end of the protective tube 2. The interior of the end cover 3 is a hollow structure, and a protective net 6 is provided inside the end cover 3. When the breeding pond is drained, the water source inside the breeding pond enters the interior of the protective tube 2 and directly flows out from the protective tube 2 and the protective net 6 inside the end cover 3, reducing the impact force of the protective tube 2 and improving the protection effect of the protective tube 2.

[0028] A connecting pipe 1 is provided at one end of the protective tube 2 away from the end cover 3, and the connecting pipe 1 and the protective tube 2 are detachably installed. A connecting pipe 1 is provided at the bottom end of the protective tube 2, and the connecting pipe 1 and the protective tube 2 are detachably installed. If the curing tube 2 is damaged, the connecting pipe 1 can be separated from the curing tube 2 to facilitate replacement of the damaged components.

[0029] A connecting column 4 is provided at the intersection of the protective tube 2 and the connecting tube 1. The connecting column 4 is a hollow structure with a threaded outer wall. A threaded groove is provided at the intersection of the connecting tube 1 and the connecting column 4. When the protective tube 2 and the connecting tube 1 are connected to each other, the connecting column 4 at the bottom of the protective tube 2 is aligned with the threaded groove opened on the upper surface of the connecting tube 1. Then, the protective tube 2 and the connecting tube 1 are tightly connected by rotating the threaded groove.

[0030] The cross-sectional diameter of the connecting pipe 1 is larger than the cross-sectional diameter of the protective tube 2. By changing the connection between the connecting pipe 1 and the protective tube 2, drainage pipes of different sizes can be connected to the connecting pipe 1. The protective tube 2 is a cylindrical structure, and a plurality of water-permeable holes are opened on the inner wall of the protective tube 2. Through the setting of the water-permeable holes, the protective tube 2 can achieve a water-permeable effect while also achieving a protective effect.

[0031] By adopting the above technical solution:

[0032] When water enters the protective tube 2 and flows out from the protective net 6, the impact on the protective tube 2 is reduced. An end cover 3 is provided at one end of the protective tube 2. The interior of the end cover 3 is a hollow structure, and a protective net 6 is provided inside the end cover 3. When the breeding pond is drained, the water inside the breeding pond enters the protective tube 2 and flows out directly from the protective tube 2 and the protective net 6 inside the end cover 3, reducing the impact force on the protective tube 2 and improving the protection effect of the protective tube 2.

[0033] Embodiment 2:

[0034] This embodiment provides a specific structure of a crayfish breeding outlet escape prevention device, such as Figure 1-5As shown, a connecting pipe 1 is provided at one end of the protective tube 2 away from the end cover 3, and the connecting pipe 1 and the protective tube 2 are detachably installed. A connecting pipe 1 is provided at the bottom end of the protective tube 2, and the connecting pipe 1 and the protective tube 2 are detachably installed. If the curing tube 2 is damaged, the connecting pipe 1 can be separated from the curing tube 2 to facilitate replacement of the damaged components.

[0035] A connecting column 4 is provided at the intersection of the protective tube 2 and the connecting tube 1. The connecting column 4 is a hollow structure with a threaded outer wall. A threaded groove is provided at the intersection of the connecting tube 1 and the connecting column 4. When the protective tube 2 and the connecting tube 1 are connected to each other, the connecting column 4 at the bottom of the protective tube 2 is aligned with the threaded groove on the upper surface of the connecting tube 1. Then, the protective tube 2 is tightly connected to the connecting tube 1 by rotating the threaded groove.

[0036] By adopting the above technical solution:

[0037] The connecting column 4 is a hollow structure with a threaded outer wall, and a threaded groove is provided at the intersection of the connecting pipe 1 and the connecting column 4. When the protective tube 2 and the connecting tube 1 are connected to each other, the connecting column 4 at the bottom of the protective tube 2 is aligned with the threaded groove opened on the upper surface of the connecting tube 1, and then the protective tube 2 and the connecting tube 1 are tightly connected by rotating the threaded groove.

[0038] Working principle: an end cover 3 is provided at one end of the protective tube 2, the interior of the end cover 3 is a hollow structure, and a protective net 6 is provided inside the end cover 3. When the breeding pond is drained, when the water source enters the interior of the protective tube 2, it flows out from the protective net 6, reducing the impact on the protective tube 2. The water source inside the breeding pond enters the interior of the protective tube 2 and directly flows out from the protective tube 2 and the protective net 6 inside the end cover 3, reducing the impact force of the protective tube 2 and improving the protection effect of the protective tube 2.

[0039] When connecting the protective tube 2 and the connecting pipe 1, the connecting column 4 at the bottom of the protective tube 2 is aligned with the threaded groove on the upper surface of the connecting pipe 1. The protective tube 2 and the connecting pipe 1 are then tightly connected by rotating the threaded groove. If the protective tube 2 is damaged, the connecting pipe 1 can be separated from the protective tube 2 to facilitate replacement of the damaged component.
